With a teen going off to college we probably need to swap their PAYG phone for something that gives them no excuse not to keep in touch. So some basic information please - can over 18s have a contract in their own names when they are relying on parental contributions/loans? I would like them to have to take responsibility for the costs.
They have an old iphone but want a newer version. What is the difference between 4, 4S and 5 and what amount of data use would you have just from automatic updates to apps? How easy is it to switch internet use off if you are exceeding your limit?
